We have written usb drivers for the pedal and joystick we are using with the QNX system. The problem is we are forced to
 restart io-usb with the following lines in rc.local to ensure that the drivers we have written can see that the devices
 are physically connected:

slay io-usb
io-usb -dehci -duhci -dohci
waitfor /dev/io-usb/io-usb

Another approach is to physically disconnect and connect the USB devices. And in fact sometimes we are forced to do this
 even with the lines above.

Do you think there is a better way to handless this situation?

Thanks...
